Edit: Looks like HD carries PEX-A and B from Apollo, so make sure what your store carries.
Uponor makes PEX-A and the Apollo found at Home Depot is PEX-B. Some fittings will only work for PEX-A and can't be used with B, but these are somewhat proprietary expansion fittings that rely on the extra flexibility of A. The good news is, you don't have those fittings. The poly fittings with stainless clench rings work with A and B as do the brass fittings that take crimp rings. These systems are safe to interchange.
The main issue with the crimp systems is the expensive tools you need to use them. You might be able to rent a tool, but I've never looked into that.
Another option are the push-on "Sharkbite" type fittings that also work with A and B. Some people shy away from putting them in walls, but they have a good safety record. On installs the crimp fittings are much cheaper, but when making changes or repairs, the extra money for a few push fittings is small in the grand scheme of the job, and they require no tools to install.
